NAME

       pmSortInstances   -  sort  performance  metric  values  on
       instance identifier


C SYNOPSIS

       #include <pcp/pmapi.h>

       void pmSortInstances(pmResult *result)

       cc ... -lpcp


DESCRIPTION

       The routine pmSortInstances may be used to guarantee  that
       for each performance metric in the result from pmFetch(3),
       the  instances  are  in  ascending   instance   identifier
       sequence.

       This  is most useful when trying to compute rates from two
       consecutive pmFetch(3) results.


SEE ALSO
